BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an assembly type packaging box capable of being transformed into a rack, and more particularly, to an assembly type packaging box capable of being transformed into a rack that can keep items like bottles of wine required to be laid for storage, in a state of being laid therein.

2. Background of the Related Art

Since a cork is soft and flexible, it is easily inserted into a neck of a bottle, and once it is inserted into the neck of the bottle, it is expanded again thereinto. Thus, the cork is usually used for a stopper of a bottle of wine. Especially, a large amount of air enters the bottle of wine through the cork to prevent the wine in the bottle from being oxidized, while a small amount of oxygen is entering the bottle of wine through the tissues of the cork for a long period of time to allow the wine in the bottle to be slowly aged. So, the cork is preferably used for the stopper of the bottle of wine.

By the way, if the cork stopper becomes dried, it is contracted and forms cracks through which outside air is rapidly absorbed, thereby making the wine undesirably oxidized and turned sour. In order to prevent the cork stopper from being dried, thus, the bottle of wine having the cork stopper should be laid during storage. Therefore, the bottles of wine in wine shops are laid on racks wherein they can be stored in the state of being laid, and in recent days, as an amount of wine consumption has been enormously increased, domestic racks on which bottles of wine are laid for storage are widely supplied and used.

However, all of general houses do not purchase such racks easily, thereby making it not easy to store the round bottles of wine in the state of being laid. Of course, they may be stored in the box wherein they are laid, which does not give good appearances and makes it difficult to store many bottles of wine therein.

Therefore, there is a need for the development of an assembly type packaging box for a bottle of wine capable of being transformed into a rack on which the bottle of wine is laid for storage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Hereinafter, an explanation on an assembly type packaging box capable of being transformed into a rack according to the preferred embodiments of the present invention will be in detail given with reference to the attached drawing.

According to first and second embodiments of the present invention, there is provided an assembly type packaging box capable of being transformed into a rack that can accommodate and keep a bottle of wine thereon, but the assembly type package box is not limited to the box for packaging the bottle of wine or the rack for displaying the bottle of wine.

Referring to FIGS. 1 to 8, hereinafter, the first and second embodiments of the present invention will be explained.

First, an assembly type packaging box capable of being transformed into a rack according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6. The assembly type packaging box includes an outer box 10 and an inner box 20. As shown in FIGS. 1 to 3, the outer box 10 and the inner box 20 each has a shape of a band having two open facing lateral sides in a rectangular parallelepiped box, and when the inner box 20 is completely inserted into the outer box 10 and closed by the outer box 10, they have a rectangular parallelepiped packaging box (See FIG. 1).

An item to be accommodated in the packaging box is disposed inside the inner box 20, and as shown in FIG. 2, when one side of the inner box 20 is pushed, the inner box 20 is separated from the outer box 10 to take the item accommodated in the inner box 20 to the outside.

As shown in FIG. 3, the inner box 20 is completely separated from the outer box 10, and after that, as shown in FIG. 4, the outer box 10 and the inner box 20 are cross-coupled to each other to build an X-shaped rack.

According to the first embodiment of the present invention, the outer box 10 and the inner box 20 each has two incision lines formed on one side of each lateral side thereof. In more detail, as shown in FIG. 3, the outer box 10 has two incision lines 11 and 12 formed on one side of one lateral side thereof and has two incision lines 13 and 14 formed on one side of the other lateral side thereof. Further, the inner box 20 has two incision lines 21 and 22 formed on one side of one lateral side thereof and has two incision lines 23 and 24 formed on one side of the other lateral side thereof.

The outer box 10 and the inner box 20 having the incision lines formed thereon are cross-coupled to each other to build the X-shaped rack, and in more detail, the incision line 11 is cross-coupled to the incision line 21, 12 cross-coupled to 23, 13 cross-coupled to 22, and 14 cross-coupled to 24.

So as to perform the cross-coupling of the outer box 10 and the inner box 20, the two incision lines (11 and 12, and 13 and 14) formed serially on the outer box 10 should be spaced apart from each other by a distance corresponding to a width d₁ between the two lateral sides of the inner box 20, and the two incision lines (21 and 22, and 23 and 24) formed serially on the inner box 20 should be spaced apart from each other by a distance corresponding to a width d₂ between the two lateral sides of the outer box 10.

Furthermore, a thickness of each of the incision lines 11 to 14 formed on the outer box 10 is set to correspond to a thickness of the lateral face of the inner box 20, and a thickness of each of the incision lines 21 to 24 formed on the inner box 20 is set to correspond to a thickness of the lateral face of the outer box 10. Herein, the corresponding thickness is equal to the thickness of the lateral side or is a little higher than the thickness of the lateral side in such a manner as to insert the lateral side into the incision line, while being not escaped well therefrom.

Also, if a length A of each incision line of the inner box 20 and a length B of each incision line of the outer box 10 are too short, the coupling between the outer box 10 and the inner box 20 is not stable, and contrarily, if they are too long, the outer box 10 and the inner box 20 are protruded upwardly after coupling, which gives bad influences on the stability and appearance. Thus, the addition of the length A of each incision line of the inner box 20 and the length B of each incision line of the outer box 10 is greater than a width I₂ between the lateral sides of the inner box 20 and is less than a width I₁ between the lateral sides of the outer box, and since the size of the outer box 10 is larger than that of the inner box 20, the length B of each incision line of the outer box 10 is longer than the length A of each incision line of the inner box 20.

Also, if the two incision lines formed serially on the lateral sides of the outer box 10 and the inner box 20 are spaced apart from each other by the same distance from the center of the lateral side of each box, as shown in FIG. 4, five space portions having similar sizes to one another are formed in the assembly type packaging box transformed into the rack, in which bottles of wine can be laid for their storage. Further, if the X-shaped rack is laid inside a drawer, a variety of items like underwear, neckties, accessories and so on can be organized well therein.

Like this, after the assembly type packaging box is transformed into the rack, a variety of items can be positioned, and if the inner box 20 is inserted into the outer box 10 again, the inner box 20 and the outer box 10 can be used again as the assembly type packaging box for packaging various items therein. However, if a fragile item like a bottle of wine is accommodated therein, the two facing lateral sides of the inner box 20 into which the item is stored are opened, so that in the process of separating the inner box 20 from the outer box 10, the item may fall down and be even destroyed.

So as to fixedly accommodate the item in the lower portion of the inner box 20, the inner box 20 has a lower fixing plate 26 having an opening formed correspondingly to the underside outer peripheral surface of the item to be accommodated therein, and so as to fixedly accommodate the item in the upper portion of the inner box 20, the inner box 20 has an upper fixing plate 8 having an opening formed correspondingly to the upper outer peripheral surface of the item to be accommodated therein, thereby allowing the item to be stably accommodated in the inner box 20.

After the assembly type packaging box is transformed into the rack, however, if the upper fixing plate 28 and the lower fixing plate 26 still exist in the space portion of the rack, they may give bad influences on the functions of the rack. Thus, desirably, they are detachably mounted inside the inner box 20, and as shown in FIG. 5, the inner box 20 has guide grooves 27 and 29 formed at the inside thereof in such a manner as to easily detachably mount the lower fixing plate 26 and the upper fixing plate 28 on the inner box 20.

Furthermore, the outer box 10 of the assembly type packaging box according to the present invention has the two open facing lateral sides, and thus, if the inner box 20 is inserted into one open lateral side of the outer box 10, it may be pushed to the outside through the other open lateral side thereof. Therefore, desirably, auxiliary members are needed to insert the inner box 20 into a given position inside the outer box 10.

As shown in FIG. 6, the auxiliary members include a protrusion 15 formed on the inside bottom of the outer box 10 and an elongated slot 25 formed on the outside underside of the inner box 20, thereby preventing the inner box 20 from being pushed inwardly over the end of the elongated slot 25. However, the auxiliary members are not restricted to the configuration of the protrusion and the slot, but may include a magnet mounted on the inside bottom of the outer box 10 and a metal or another magnet having opposite polarity to the magnet mounted on the outside underside of the inner box 20, thereby inserting the inner box 20 into the given position inside the outer box 10 and preventing the inner box 20 from being escaped from the outer box 10 easily.

The inner box 20 positioned inside the outer box 10 is drawn from the outer box 10 by pushing one lateral side thereof, and alternatively, the inner box 20 is drawn from the outer box 10 by taking a handle H disposed on one lateral side of the inner box 20. If the handle H is mounted, as shown in FIG. 5, it is disposed at the center of one lateral side of the inner box 20.

According to the second embodiment of the present invention, as shown in FIG. 7, there is provided an assembly type packaging box capable of being transformed into a rack that is provided with an outer box and two inner boxes adapted to be inserted into the outer box. In more detail, the assembly type packaging box capable of being transformed into a rack includes: an outer box 10 having two open lateral sides facing each other; a first inner box 20 having two open lateral sides facing each other and adapted to be inserted into one lateral side of the outer box 10; a second inner box 30 having two open lateral sides facing each other and adapted to be inserted into the other lateral side of the outer box 10.

The first inner box 20 and the second inner box 30 are inserted serially into the outer box 10 and closed by the outer box 10 to have a shape of a generally rectangular parallelepiped, and after the separation of them from the outer box 10, they are cross-coupled to one side and the other side of the outer box 10 to build an X-shaped rack, as shown in FIG. 8.

Unlike the first embodiment of the present invention, the second embodiment of the present invention is configured to insert two inner boxes into one outer box, and therefore, the outer box is two times the size of the inner box. Also, the first inner box 20 and the second inner box 30 are cross-coupled to one side and the other side of the outer box 10, and unlike the outer box in the first embodiment of the present invention, therefore, the outer box in the second embodiment of the present invention has two incision lines formed on both sides of the lateral sides thereof. With the exclusion of the above-mentioned configuration, the second embodiment of the present invention is almost the same as the first embodiment of the present invention.

In more detail, the auxiliary member and the upper and lower fixing plates as mentioned in the first embodiment of the present invention are provided in the second embodiment of the present invention, and since two inner boxes are positioned serially inside the outer box 10, especially, the handle H is desirably mounted on the lateral sides exposed to the outside of the first inner box 20 and the second inner box 30 so as to easily draw the first inner box 20 and the second inner box 30 from the outer box 10.

The incision lines formed on the first inner box 20 and the second inner box 30 and on the outer box 10 are the same as in the first embodiment of the present invention, but the addition (2×A) of a length A of each incision line of the first inner box 20 and a length B of each incision line of the second inner box 30 is equal to a length obtained by subtracting the addition (2×B) of each incision lines formed on both sides of the lateral sides of the outer box 10 from a width of the lateral side of the outer box 10, such that when they are transformed into the rack as shown in FIG. 8, the first inner box 20 and the second inner box 30 can be stably coupled to the outer box 10.

In this case, the first inner box 20 and the second inner box 30 have coupling members formed on the lateral sides S1 and S2 facing each other at the time of being transformed into the rack, and the coupling members include magnets or a protrusion and a groove coupled to each other, such that the rack can be built more stably.

Since the rack built according to the second embodiment of the present invention is two times the length of the rack in the first embodiment of the present invention, it is very stable when items having long length like bottles of wines are kept therein.

While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims.
